焦炭冲天炉附加煤粉这项新技术正在全国逐步利用和发展。它对使用低质焦碳,提高焦铁比,提高铁水温度和加快熔化速度,都有一定的作用。77年底,我厂根据外地经验,将原来5吨/小时焦炭冲天炉进行改造,并试验20多炉次,取得一定效果。现将我厂焦炭冲天炉附加煤粉小结如下。 Coke cupola additional pulverized coal This new technology is gradually used and developed throughout the country. It has a certain effect on the use of low-quality coke, increase the iron-iron ratio, increase the hot metal temperature and speed up the melting rate. By the end of 77, according to field experience, our factory transformed the original 5 t / h coke cupola and experimented more than 20 times to obtain some results. Now I plant coke cupola attached to the following summary of pulverized coal.
